Miller Muffler & Suspension, Dallas TX

Final edit: while collin did tell me to "roll my hunk of junk into a lake, " I've had other better experiences with them and do recommend them. Especially over pronto for exhaust work. However I won't be bringing my truck there for the previously mentioned alignment, which im sure both of us are more than happy with.

Honesty! Need I say more? Danny's Import Srv recommended I call Miller Muffler and thankfully there's a location in Plano. Calling Miller was the best decision I could have made. Thanks guys!

Had a lift kit installed on my Gladiator. Neat price on kit and best shop rate to install. Can’t beat that. Nice people to work with.

Shout out to Collin and his team at Miller Muffler in Dallas. I knew my exhaust was in bad shape and was just putting it off until today when it decided to fall apart. Being a Saturday, I wasn't expecting to get it fixed. But I called Miller Muffler at 2pm and they said bring it in. My truck was on the rack at 220 and I was paying at 300pm. I am extremely happy with my exhaust and I felt the price was very fair. They didn't try to upsell or talk me into anything I didn't need. Collin, Thank you and your team very much for the great service and awsome work. You guys killed it.

The best of the best! Been bringing my cars here for the past year for exhaust work and other goodies and they are phenomenal! Colin one of the owners is super nice and always a pleasure to deal with. You will NOT be disappointed!

Collin Miller Muffler have a solid integrity and great expertise. I’m glad to have met them and to be a customer.

They aligned my 21’ lifted 4Runner with precision.

I highly recommend! We had the engine light on due to the O2 sensors. They ordered and installed new sensors all in 1 hour. We drove 60 miles out of the store and just passed the annual inspection.

Very good service both times I went. Don’t seem to charge that much and are fast at their craft. So far so good

Dropped my truck off at 8am right when they opened with a decrepit exhaust barely holding together and by 11am they finished installing by upgraded Flowmaster system. The guy who helped me gave me options of a good direction to go for exhaust that fit in my budget and gave an accurate estimate. They’re fast and friendly and I would recommend anyone to them.

Don't really know where to begin! I would love to commend Collin an Josh for their courtesy an professionalism! I had an exhaust installed on my 92 Corvette! The wrong one was sent! Collin got on the phone and had the correct one shipped the next day! It's a pleasure to spend money with a buisness that has courtesy an Integrity! For you pick up Gents they do it all! Exhaust, lift kits tires really there isn't any place to go except here!

I was in Frisco for the Holidays and my catalytic converters were stolen while parked at the hotel. Colín got me in and out with new cats, O2 sensors, and a borla exhaust in less than three hours. I’m very appreciative of this shop for helping me in a time of need.

Came in at 12: 15 and they had me out by 12: 45 after diagnosing the issue with my downpipe. Fixed the cracked bracket and filled in the logo which was causing an audible grinding sound when accelerating. Very fair price and would 10/10 recommend. I'll be definitely coming back for future repairs/maintenance

Great service! Fast work the on the job I love my new exhaust can’t wait to come back! You guys should really come here it’s fast and good prices!

Absolutely the best customer service and fastest repair ever experienced. We had our catalytic converter stolen off our motor home and found out about it on a Friday afternoon just two days before starting a 40 day, group trip. Miller’s had parts in stock (everyone else had parts on back order) and got us in the next day. Took 30 minutes and we were fixed and back on the road…. Didn’t have to cancel our prepaid trip. Miller’s is the best.

The best! Fixed my issue in a short period of time. Thank you guys my genesis coupe 3.8Turbo is now running beastly

Mr. Collin & his staff members were great in helping me fully understand the exhaust issue my suv had occurred. I paid a lesser price tag than I expected to fork over.my ride runs nice & smooth now, thank you Miller team of mechanics! I highly recommend Miller Exhaust & Suspension to anyone experiencing a vehicle exhaust issue. These guys are very knowledgeable & know what they're doing. Thanks again.

Collin and gang did a fantastic job installing an after market Borla exhaust system on my 2021 F150 powerboost. Listened to exactly what I wanted, and executed. Outstanding experience. Would highly recommend for any project.

Came in to get a custom J-pipe added in to my existing setup and to replace some things poorly installed from another popular exhaust shop in the Plano area. Collin hooked me up with a great price and awesome work! Will be recommending them to anyone that needs exhaust work in the future.

Unbelievable, I have never seen such prompt service in my life.

I called for an appointment and walked out in less than an hour; I cannot recommend enough. They were extremely polite and made an immediate diagnosis. The sounds my car was making for ages and I had grown accustomed to were finally gone. I am so glad to have brought my car here.

I was charged just for parts, and I sincerely hope that everyone can experience outstanding service like this when dealing with car problems.
